Buy 3 McCormick vanilla extract on sale at Giant Eagle 2/$7 (the small bottle) total $10.50 for 3. Use 3- $1 off coupons from 3/14 Sunday newspaper insert. Spend $7.50 out of pocket. You will get a $2 catalina back from Giant Eagle and a $2.50 catalina back from McCormick. That's like spending $1 a bottle for vanilla extract.
Also if you buy 2 bags of Domino sugar at $3 ea and 2 cans of Carnation evaporated milk at $1 ea ($0.50 coupon in 3/21 newspaper insert) you will get another $2 catalina back. I would recommend doing these in two separate transactions and you can use the first catalinas to pay for the second.
